Industrial Manslaughter South Australia: 20 Years Prison, $18M Fines & Psychosocial Hazard Risks for Directors

Executive Summary

On 1 July 2024, South Australia introduced industrial manslaughter laws carrying maximum penalties of 20 years imprisonment for individuals and $18 million fines for corporations. Six months earlier, in December 2023, SA implemented psychosocial hazard regulations requiring businesses to identify and control 14 categories of psychological workplace risks.

The timing matters. SafeWork SA has made clear that a worker’s psychological health is just as important as their physical health, and the industrial manslaughter offence applies to any worker death caused by reckless or grossly negligent conduct, with no exception for deaths linked to psychosocial hazards.

The December 2025 Defence conviction, the first time a Commonwealth employer has been convicted of failing to manage psychosocial risks under federal WHS laws, following a worker's suicide, demonstrates this isn't theoretical. Mental health failures can kill, and directors face personal criminal liability including imprisonment when gross negligence in managing psychosocial hazards results in death.

What Is Industrial Manslaughter in South Australia?

Industrial manslaughter occurs when a person or body corporate conducting a business or undertaking engages in conduct that causes the death of a worker, and the conduct constitutes:

• Gross negligence (such a great falling short of the required standard of care that it merits criminal punishment), OR
• Reckless conduct (awareness of risk but proceeding anyway)

Maximum Penalties:

• Individuals: 20 years imprisonment
• Body corporate: $18 million fine
• Since 1 September 2024, it has been illegal in South Australia to insure against WHS fines, a fine must be paid by the business or person convicted, not passed to an insurer

The Psychosocial Connection: Mental Health Hazards Can Lead to Industrial Manslaughter

South Australia’s regulatory timeline:

• December 2023: Psychosocial hazard regulations commence
• July 2024: Industrial manslaughter offence introduced (6 months later)
• SafeWork SA: “A worker’s psychological health is just as important as their physical health”

The implication: a worker’s death caused by reckless or grossly negligent failure to manage psychosocial hazards, including a suicide linked to unmanaged workplace hazards, could meet the test for industrial manslaughter.

The 14 Psychosocial Hazards South Australian Employers Must Manage

The Managing Psychosocial Hazards at Work Code of Practice identifies 14 hazard categories. Directors must demonstrate these are identified, assessed, and actively controlled:

Work Demands and Design:

• Job demands (excessive workload, time pressure, emotional demands)
• Low job control (inability to influence decisions affecting work)
• Poor support (inadequate supervisor or peer support)
• Lack of role clarity (unclear expectations or conflicting demands)

Organizational Factors:

• Poor change management (restructures, redundancies without support)
• Inadequate reward and recognition
• Poor organizational justice (unfair or inconsistent treatment)
• Exposure to traumatic events or material

Interpersonal:

• Violence and aggression (from public, customers, or co-workers)
• Bullying
• Harassment (including sexual harassment)
• Conflict or poor workplace relationships

Environment:

• Remote or isolated work
• Poor physical environment (inadequate facilities, temperature, noise)

Critical understanding: These aren't abstract concepts. They're routine workplace conditions that, if unmanaged, can cause serious psychological harm, including suicide.

The Defence Case: Psychosocial Failures Leading to Worker Death

In December 2025, the Commonwealth Department of Defence became the first Commonwealth employer convicted of failing to manage psychosocial risks under federal WHS laws, after a worker's suicide. It was prosecuted as a breach of the WHS duty of care, not as industrial manslaughter, but it shows regulators will take psychosocial failures linked to a death to court.

What Happened:

A 34-year-old RAAF technician took his own life while on duty in July 2020 after being placed on four separate Work Plans (performance management) over six months.

What the Prosecution Established:

• Defence had policies identifying that Work Plans could constitute psychosocial hazards
• Supervisors were not trained to recognize or manage these hazards
• No support was provided despite obvious signs of psychological distress
• At no point did supervisors refer the worker for assistance or provide relief
• Having policies meant nothing because they weren't applied in practice

The penalty:

• Department of Defence: $188,000 fine

Critical lessons for South Australian directors: Routine HR processes, performance management, disciplinary procedures, restructures, are psychosocial hazards. Gross negligence in managing them can result in industrial manslaughter charges if death occurs.

Could Psychosocial Failures Lead to Industrial Manslaughter in SA?

Legal experts and regulators increasingly view gross negligence in managing psychosocial risks resulting in death as meeting industrial manslaughter thresholds. Consider these scenarios:

Scenario 1: Sustained Workplace Bullying Leading to Suicide

Multiple employees report that Manager X is systematically bullying Worker Y. HR receives documented complaints over 6 months. Management takes no meaningful action. Worker Y takes their own life.

Industrial manslaughter elements:

• Death of worker: Yes
• Caused by conduct of business: Yes (failure to manage reported bullying)
• Gross negligence: Likely (awareness of serious risk, repeated warnings, no action)
• Result: Directors could face industrial manslaughter prosecution and 20 years imprisonment

Scenario 2: Excessive Workload Causing Fatigue-Related Death

Company routinely requires workers to work 70-80 hour weeks despite complaints of exhaustion. Worker has micro-sleep while operating machinery, resulting in fatal accident.

Industrial manslaughter elements:

• Death: Yes
• Caused by business conduct: Yes (excessive job demands causing fatigue)
• Gross negligence: Likely (known extreme workload, obvious fatigue risks, no controls)
• Result: Industrial manslaughter prosecution highly probable

Scenario 3: Poorly Managed Restructure Leading to Suicide

Company announces major restructure. Workers receive redundancy notices with no support, counseling, or transition assistance. Worker experiencing acute psychological distress takes their own life.

Industrial manslaughter elements:

• Death: Yes
• Caused by business conduct: Yes (change management without psychosocial safeguards)
• Gross negligence: Arguable (restructures are known psychosocial hazards, no support provided)
• Result: Prosecutors could pursue industrial manslaughter charges

Why Psychosocial Industrial Manslaughter Prosecutions Are Likely in SA

1. SafeWork SA’s Stepped-Up Enforcement

SafeWork SA’s 2024–25 enforcement data shows its highest number of convictions in more than a decade:

• Record fines totalling $2.37 million
• 7,715 workplace site visits (up from 6,813 the previous year and 5,122 in 2022–23)
• 18 convictions across 14 matters, the most since 2013–14
• A record $840,000 fine against JMA Engineering (November 2024) following a worker's death, the first SA conviction for a Category 1 reckless conduct offence

2. Psychological Injury Claims Demonstrate Ongoing Harm

• Mental health claims up 161% over past decade
• Median psychological injury claim: $67,400 (vs $16,300 across all serious claims)

3. Clear Regulatory Guidance Eliminates Defenses

The Code of Practice provides detailed guidance on:

• Identifying the 14 psychosocial hazard categories
• Assessing risks and implementing controls
• Monitoring and reviewing effectiveness
• Directors cannot claim “we didn't know” when regulatory guidance is explicit

4. Federal Precedent (Defence Conviction)

The Defence case establishes:

• Psychosocial hazards causing death are prosecutable WHS failures
• Having policies is insufficient, implementation matters
• Routine HR processes are hazards requiring active management
• Courts will impose significant penalties for psychosocial failures

What Directors and Employers Must Do Now

Step 1: Identify Psychosocial Hazards

• Conduct psychosocial risk assessments across all work areas
• Survey employees about workload, support, fairness, conflict, harassment
• Review high-risk processes: performance management, restructures, complaint handling
• Analyze workers compensation psychological injury claims for patterns

Step 2: Assess Risks

• Determine which hazards could cause serious psychological harm
• Identify workers or roles most at risk
• Evaluate adequacy of current controls

Step 3: Implement Controls

• Redesign work to reduce excessive demands
• Train managers to recognize psychological distress
• Provide EAP and mental health support
• Ensure HR processes include psychological safety safeguards
• Create confidential reporting mechanisms for psychosocial concerns

Step 4: Monitor and Review

• Track leading indicators (complaints, stress levels, workload concerns)
• Monitor lagging indicators (claims, absenteeism, turnover)
• Respond immediately to psychosocial concerns raised
• Document everything, evidence of action protects directors

The Platform Problem: Why Traditional Systems Fail

Most organizations manage psychosocial risks across scattered, disconnected systems: incident reports in one platform, employee surveys in another, workers compensation claims tracked separately, performance management in HRIS, grievances in email folders, exit interviews in spreadsheets.

This fragmentation makes it impossible to identify patterns. When multiple low-level complaints about the same manager appear across different systems, no one connects the dots. When restructure announcements correlate with spikes in psychological distress, the pattern remains invisible.

Result: Directors cannot demonstrate due diligence because they don't know what they don't know.

How Salus Enables Genuine Psychosocial Risk Management

Guided reporting, any hazard

An employee raising a psychosocial concern, bullying, excessive workload, a poorly handled restructure, is guided through compiling a clear report by an AI-led conversation, never a form, anonymous or identified, informed by the relevant legislation and the organisation's own policy.

Obligation mapping for officers

The moment a report is received, the responsible person is shown exactly what they're required to do for that report type, sourced from legislation and policy, directly relevant to the due diligence obligation this article describes.

Evidentiary logging

Every action taken on a report is timestamped and individually signed, building the documented record a court looks for when assessing whether due diligence was genuinely exercised in the lead-up to a serious incident, not just claimed after the fact.

Policy gap analysis

Existing policies are assessed against current legislation to surface gaps before an incident, not after, directly relevant to the scenarios described above, where a documented complaint or known risk went unaddressed.

Conclusion: Paper Policies Won't Protect You From 20 Years Prison

South Australia’s industrial manslaughter laws carry up to 20 years imprisonment and $18 million fines when reckless or grossly negligent conduct causes a worker’s death. Psychosocial hazard regulations took effect six months earlier, in December 2023, and nothing in the offence excludes deaths caused by unmanaged psychosocial hazards.

The Defence conviction proves having policies is insufficient. What protects directors is evidence those policies are genuinely implemented, monitored, and enforced. Workers must be able to report concerns safely. Leadership must identify patterns before they escalate. Response must be immediate and documented.

Directors who wait for the next industrial manslaughter prosecution will find themselves explaining to courts why they didn't act when workers compensation psychological injury claims were rising and regulatory guidance was clear.
